, Application filed December 27, 1927. Serial No. 2%,597.

This invention relates to headlights of automobiles, trucks, motorcycles or other vehicles, the particular object of the invention being to construct a headlight so as to prevent glare which is objectionable to approaching cars. An advantage of the construction shown and described herein is that the headlight constructioneificiently lights the road ahead of the car for a considerable distance without throwing the light rays in an upward direction. Even when the car is on an upgrade, as in passing overa hill, the motorist'in the approaching car is not subjected to objectionable glare.

The device shownherein is highly efficient and serves the designated purposes without expensive or complicated equipment. It is shown in its preferred form in the drawings and description hereto appended, but the invention is not necessarily limited to err.- act conformity with the details but may be modified within the scope of the invention as limited by the prior art and .by a fair construction of the claims.

In the drawings:

Figure 1 is a horizontal section through the headlight; and r p Figure 2 is a front elevation of the headlight; I

The headlight is mounted upon a usual bracket 1, to which is attached the body 2 of the headlight which is in the form of an elongated cylinder or barrel.. The front of the headlight is provided with the usual lens 3 held in place by the ring 4. In the rear of the cylindrical headlight is located the lamp 5 which is located at the center of the reflector 6 which may be of any usual form. The interior of the headlight is provided with a casing 8, the surface of which is non-reflecting. In the central portion of the cylindrical headlight body are located two parallel shutters or screens 9 and 10, the lower screen 10 being slightly longer than the upper screen. The under surfaces reference to the reflector.

of these creens are not reflecting and the forward edge of the screen 9 is-spaced slightly above the inner edge of the screen 10' so that only a small beam or shaft of light is emitted directly from the lamp. The rays reflected from the lower portion of the reflector 6, and which are therays which normally form the glare, are intercepted by the screens 9 and 10.

It will be observed that the cylindrical portion ofthe lamp in front of the reflector is substantially equal to the diameter of the 'reflector, and this construction confines any lamp, and horizontally arranged but forwardly and downwardly inclined shutters located in the barrel in front of the lamp at the center of the headlight, the under sur- I faces of which are dull and non-reflecting, the length ofthe barrel in front of the' reflector being not less than the diameter of the reflector and the inside surface of the barrel being non-reflecting.

2. A headlight having an elongated, cylindrical barreha lamp located near the rear of the barrel, a reflector at the rear of the lamp, and horizontally arranged but forwardlyand downwardly inclined shutters located in the barrel at the center of the headlight, the'length of the barrel in front of the reflector being not less than the diameter of the reflector and the inside of the barrel being non-reflecting GEORGE A.
